Filed: 1975-03-04
Abstract: 1474497 Yarn texturing air jet ENTERPRISE MACHINE & DEVELOPMENT CORP 4 March 1975 [21 June 1974] 9019/75 Heading D1F A yarn texturing air jet having an elongated housing 10 with a central bore 11 for passage of multifilament yarn Y and means 20 for directing pressurised air into bore 11 to impart crimps curls and loops to the filaments is characterised by its combination with a baffle 30 in the form of at least a half cylinder, the baffle being supported on the air jet for vertical and horizontal (in the direction of bore 11) adjustment so that as the yarn leaves the air jet it is engaged by the solid surface of the baffle and directed in a semicircular bath. Some of the pressurised air moves in a semicircular path with the yarn and some is deflected away from the yarn and baffle, creating a lower pressure region which causes the yarn to leave contact with the baffle for part of its semi-circular path. The textured yarn has a round cross section. The air jet shown is described and claimed in Specification 1465433. The horizontal position of the baffle is adjusted by sliding bar 33 in block 32 and the bar 33 is locked by screw 35. Vertical adjustment is obtained by turning head 41 of threaded shaft 40, the shaft being locked by screw 43. A guide pin (44, Fig. 1 not shown) fits into a vertical channel in the baffle to ensure vertical movement. The baffle may be a full cylinder. 1500 to 4000 denier yarn is readily textured. Core and effect and slub yarns may be obtained.

Abstract: 1,183,782. Printing apparatus. BEBOPLASTIK G.m.b.H. 26 Feb., 1968 [23 March, 1967], No. 9117/68. Heading B6C. The developed surfaces of articles with non- circular cross-sections are printed in a machine in which each article is mounted on a holder which is resiliently urged towards the printing surface which may either be the offset blanket of a rotary offset unit or the intaglio cylinder of an intaglio unit. In the described embodiment, holders 15 are rotatably mounted on an intermittently rotatable turret plate 7 and at the printing station each holder shaft 13 is aligned relative to the printing surface by a stop 4 on the machine frame engaging a square member 3 keyed to the shaft. Subsequent to such alignment the shaft is rotated through a friction disc 5, also keyed to the shaft, such that the locked holder, and hence the article, rotates through one complete revolution. The disc 5 and the article rotate through friction drive from the printing surface 25 which is an offset blanket segment resiliently mounted on a cylinder 10. If desired the disc 5 may be replaced by a toothed gear which engages similar teeth on the printing surface. The surface 25 may be an intaglio surface mounted on the cylinder 10.

Abstract: 661,300. Skates. GERRITS, P. H. April 4, 1949 [April 5, 1948], No. 9168/49. Class 132 (i). Steerable roller skates comprise a resilient deformable member operatively connected to each pair of wheels, and means connecting the foot plate to such member to bend the same and swivel the wheels for steering. As shown, each pair of wheels is carried by a pillar 8, 9 connected to the foot plate 6 by a universal joint 7. Extending through slots in the pillars is a resilient blade 13, which is connected at its centre to the foot plate by brackets 14. In order to turn, the skater leans so that the foot plate is inclined to the horizontal whereby the resilient blade 13 assumes an arcuate path thus rotating the pillars 8, 9 to orientate each pair of wheels to a curved path. The foot plate and resilient blade may be made adjustable for length. The Specification as open to inspection under Sect. 91 states that the arrangement is applicable to ice skates. This subject-matter does not appear in the Specification as accepted.

In a ferromagnetic laminated slot wedge for electrical machines, the stack of laminations of which the wedge is formed has a longitudinally extending groove and is provided at each end with a rigid end piece; a tension bolt is located in the groove and extends through bores in the end pieces, so that when the bolt is tightened the laminations are pressed together. As shown, laminations 1 forming a slot wedge and having recesses 6 together forming a groove, are secured and pressed together between two end pieces 2 by a tension bolt 3 which engages the end pieces. Preferably, the end pieces 2 or the tension bolt 3, or both, are made of material which is a poor conductor or is non-conducting, electrically, and/or non- magnetic. Preferably, as shown, the parts on either side of recess 6 are connected by a narrow web portion 7. Preferably, the whole wedge is electrically insulated. The recess 6 may have a cross-section which is circular (fitting the bolt 3), instead of trapezoidal as shown, it may communicate by a slot with the top of the wedge.

Title: Improvements in and relating to devices for protecting electrical circuits from excessive heating
IPC: H01H71/20
Filed: 1924-04-11
Abstract: 222,776. Calor-Elektrizitõts-Ges., and Dreyer, O. April 11, 1924. Thermal cut-outs; cases; fuse boards. - In thermal cut-outs a reversible thermal element is provided having a contact rod retained in position by easily fusible metal which, when softened by heat, is moved by a spring to complete a circuit and so disconnect the supply, after which the element may be reversed for a subsequent operation. The cut-out shown in Fig. 1 has a plug 4 of insulating material with a metal contact screw 3 engaging a socket 6 connected to a terminal 5 in the insulating base 1. A contact rod 10 with enlarged ends 10<a>, 10<b> is normally held down against the action of a spring 14 connected to the terminal 12 by being soldered to the thickened wall of a metal tube 7 mounted in the central aperture of a removable heating coil 2 which is normally in circuit. When abnormal current traverses the coil 2 the heat produced melts the solder and allows the spring 14 to move up the rod 10 to engage an overhanging fixed contact 17. This may produce a shortcircuit in the controlled circuit (Fig. 6) allowing fusible cut-outs 18, 19 to disconnect the supply, or, alternatively, may complete the trip circuit of an automatic circuit-breaker. After operation of the cut-out the coil 2 together with the pin 10 and sleeve 7 is removed from the body 4 and reversed to be in preparation for subsequent operation. To prevent shock by contact with the projecting live end of the rod 10 while the cut-out is being screwed home, a spring-pressed intermediate member 20, Fig. 2, may be placed between the contacts 10 and 17 and so arranged that it is only in contact with the rod 10 during release. Fig. 4 shows a cut-out 4 mounted with fusible cut-outs 18, 19 in a casing 25 with hinged lid 26 the contact 17 being mounted on the inside of the lid. The contact 17 is made dead while the casing is open by arranging that its lead 27 touches a contact 28 on the inner wall of the casing 25 only when the lid is closed. In a modified form of cut-out (Fig. 7) the contact pin 10 and tube 7, Fig. 8, may be removed for reversal without disturbing the heating coil 2. In this form the spring 30 holds the upper end of the tube 7 against the shoulder 35 of the bush 34.

Class 68(1) Structually incorporated in the jetting head of hydraulic mining equipment are means that allow of observation of the action of the jets causing the hydraulic mining of a stratum so that the head can be raised, lowered and rotated about a vertical axis as a result of this observation so that the stratum can be mined with the maximum of efficiency. The observation means may consist of a chamber having viewing ports that is so constructed in the head that the chamber is accessible from ground level to an operator, a television circuit, or optical means. Vertically directed jets 39 enable the head to be sunk into the ground, and horizontally directed jets 37 enable a stratum to be mined out. The mineral is either sucked into the head and pumped up to the surface or is carried upwards by buckets on an endless chain reaching up about the head to ground level. At the bottom of the head may be mounted a bladed cutter disc rotatably driven about a vertical axis.
